To all whom it may concern.'

it Ilrnown that I, ORRELL ASHTON, a citizen of the United States, residing at Lawrence, in the county ofEsseX and Commonwealt-h of Massachusetts, have invented certain Improvements in Machines for Operating upon the Toe `Portions of Boots or Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters o the drawings indicating like parts in the se eral figures.

This invention relates to machines for operating upon the toe ortion of a boot or shoe after lasting, to p ace that part of the d shoe in propercondition for subsequent'l operations Heretofore, it has been customary to trim off by hand projecting edges of the upper l ability of bringing the outersole ,into close and economically.

and even relation to the upper and innersole,

and from the necessity of preventing these projecting edges from interfering with sewlng mechanism employed'subsequently to lasting It is the object of my invention to construct a practically effective machine' capable of performing this operation rapidly To this end I'employ, in a machine embodying my invention, a tool for separating from the toe part of a shoe the surplus material to be removed, yand means for controlling the position of the shoe while being presented to and acted upon by the tool. This means is preferably so constructed and arranged that a shoe may be quickly and accurately brought into positibn to be operated upon. I refer to use a continuously actuated tool, and .preferablythe tool and positioning means are relatively movable so that the relation of the shoe to the positioning means need not be changed while the tool is acting. It is desirable that the relative movement be such that the shoe ma rbe r resented to the positioning means while wit lout the path of thi-,tool. rangement is referably such that the surplus stock to be removed is brought gradu- The arthe preferred embodiment of the invention, I have provided a gage movable beneath a rotary cutter in a plane parallel to 'the axis of the cutter. The gage is shaped to receive the toe part of a shoe and is arranged to permit the projections on said toe part to eX- tend above the upper surface of the gage. A rest is provided adjacent to the acting part of the gage to receive the toe tip. Ih the movement of the gage beneath the cutter, the projections on the toc part are brought into the path of the cutter and are trimmed off evenly. The shoe is held by the operator against the rest and gage and is moved forwardly with them into operative relation to the cutter, the rest and gage beingreturned by means tending to keep them in their ini-- tial position.

Other features of the invention will be hereinafter described.

In the drawings Figure 1 is a view in front elevation of a machine forming one embodiment of my invention; Fig. 2 is plan view of said machine; Fig. 3 is a view in side elevation of the same: Fig. 4 is a det ail view of a portion; Figs. 5 and 6 show the toe part of a shoe before and after being operated upon, res ectively.

n the machine herein illustrated, which constitutes the preferred embodiment of the invention, a rotary cylindrical cutter 1 shaft 2, are arranged between the. standards 4 and 5, and together withthe belt shipper 12 serve vas a convenient means Jfor actuating the cutter 1.

A frame 14 is arranged below the cutter l. The frame 14' .is pivoted at its rear end upon bearings 16 carried by a bracket 18 projecting from. the standard 4. The forward end of the frame is clamped in fixed position by a bolt 20 passing through a slot in the frame and entering the standard 4. A set screw 22 vertically adjustable in the forward end of the frame 14, and arranged to bear upon a lug on the standard 4, serves to permit the frame 14 to be. accurately adjustedwith reference to the cutter 1. i

'The frame 14 is provided with'guideways constructed to support a' plate 24 and permit said 'plate to be moved oack and forth beso l sto 40 is removably secured in the plate 24,

i i neaththe cutter 1 in an approximately horithe size 'of the recess.

vzontal path. As shown t e plate 24 is provided with grooves in its side edges and strips 26 are removably secured to the top 'Farce of the frame 14 and arranged in said grooves. The forward end of the platev24 is provided with a recess 27, as shown in Fig. 4. A gage is mounted upon the upper face of the plate 24, having its acting part, against which the toe part of the shoe to be trimmed isheld, located above the recess 27.l This gage comprises two sections 28, forming between them a recess of the shape of the tope of a shoe, and relatively adjustable to vary H desired the ga e may be made in one piece and be removab y secured in vposition so that incase a change in width lof the recess lbe required a diierent gage may be substituted.

A toerest 30 is secured to the lower face of plate 24 by screws 32 passing through slots 1n the toe rest, said slots permitting adjustment of.y the t'oe rest longitudinally of said plate. The acting Aface of the toe rest inclines rearwardly', .and is somewhat concave in horizontal section.

' A spring '34 is arranged to hold the plate towards the Jfront of the machine, this spring being connected to a projection 36 on the plate 24, and to a lug 38 on'the frame 14. A

an enters a slot 42 in the frame 14 to limit movement of the plate 24.

' The gage sections 28 are secured to arms 44 pivoted at 46`upon the low'er Jface of the 'plate 24. Apertures' 47 in the plate 24 permit movement of the sections 28 and arms 44 upon the plate 24. A spring 48 arranged between said arms 44 tends to move the gage sections apart, and a sto 50 arranged be- -tween the rear ends oi sai( arms limits sepa'- rating -movement of the gage. sections. The stop 50 is rotatably supported upon the plate 24 and is provided with faces arranged at different distances from its-axis, the construction bcing such that the effective width of the stop 50`may be adjusted by rotating the stop to bring diiierent faces into contact with 'the arms 44, said arms being maintained in engagement with said stop by the spring 48.

, A guard 52 is illustrated supported upon the standard 4 and arranged over the cutter to prevent accidental contact with the cutter. f

A pin 54 is shown slidably mounted in the stan( ard 5, said pinbcing arranged to enter a hole in the pulley 10 to lock said pulley and cutter is preferably towards .the w shaft 2 from rotation when it isdesiredto remove the cutter 1.

"Phe movement of the acting art of the lieel. With thisl movement of the cutter the trimmed ends on the upper are smoothed down in the directionoi the heel and caused to lie llat on 4toe tip against the rest.

the innersole,v and-any other objectionable projections -on thetoe part, such as lasting tacks which have `been improperly inserted, are inclined towardsthe heel. A further ad- `vantage of this feature is that the action of the cutter tends, todrawtlie upper tightly over'the toe tip and to remove wrinkles or` vbunches in theupper at this point. It will 'be seen that the repeated strokes to which the toe partis subjected -in the gradual ref 4moval of surplus stock have a considerable tendency to smooth and draw the upper towards the heel.

I regard the arrangement by which4 theA projecting portions Yare .gradually brought into the path of the cutter and removed by a vrepeated action of the cutter as ofi'mportance apart from'the direction of movement of the cutter. which the projecting portions are gradually 'removed is advantageous in that the trimming operation .is lsecured with'less tendency to disturb the parts of the-shoe adjacent to those being removed.

The u per faces of the gage -sections 28l are preferab y arranged in a plane4 as near as possible to the acting edge of the cutter, so thatthe cutter will trim closely tn said upper faces.A The acting part oi the gage sections is shown as beveled to a thin edge to permit the Such an arrangement by path of the cutter-'to be in close relationto4V y the bottom of the shoe. l In the operation of the machine shown, the

'operator places a shoe with its toe tip bear- I ing ,against the rest 30 and the upper bearing onthe edge of the recess formed between the gage sections 28. It will bc'understood that at this stagethe shoe-fis-` without the path IofI the cutter. 'lhe slice is then moved with the yielding gage and rest bencatlrtheacting face of the continuously actuated cutter into operative relation to thecutter, andthe projections extending above the top face of the gage sections 28 are trimmed oll.- The presence of lasting tacks among these projections interferes in no way with the operation of the machine, as they are trimmed voil' with the other projections. lt will be 1observed that the movement of the rest 3,() and gage into.

operative osition is 'cau-sed by pressing the of importance in'securin'g a rapid trimming operation. The rest 3() also au-ls thc operator in quickly bringing thepart ol' the shoe to l regard this icaturc rest insures that the toe part ol the shoe shall the gage sections 28. 'lhcsegage sectionsare adjusted to make the recess.'betwecn them somewhat narrower than ilu!y toe par( of the boot or shoe to be lriunned. 'lhc rest 3() may bc adjusted longitudinally ol' the plate 24 whenever a dillluccm-c in size or vbe introduced a sulli-icnt distance bencalh.'

formpi the shoe to be trimmed requires such adjustment in order to bring the toe part into correct position longitudinally oi the gage sections 28. It will be observed that the depth oi cut oi' the cutter is determined by thel position which is given the frame 14. By adjusting the screw 232 this position may he varied o cause the cutter to trim more or less closely to the sole of the shoe. v
